En la última versión de Red Hat (6.0), encontré un problema a la hora de instalar percona (mysql), que no fue otro que incompatibilidades con el software preinstalado del sistema con el nuevo servidor de base de datos, en su versión 5.5.
shell> yum install Percona-Server-server-55.x86_64 ... Transaction Check Error: file /usr/lib64/libmysqlclient.so from install of Percona-Server-shared-55-5.5.16-rel22.0.189.rhel6.x86_64 conflicts with file from package Percona-Server-shared-51-5.1.59-rel13.0.325.rhel6.x86_64 file /usr/lib64/libmysqlclient_r.so from install of Percona-Server-shared-55-5.5.16-rel22.0.189.rhel6.x86_64 conflicts with file from package Percona-Server-shared-51-5.1.59-rel13.0.325.rhel6.x86_64 file /usr/lib64/mysql/plugin/libfnv1a_udf.a from install of Percona-Server-shared-55-5.5.16-rel22.0.189.rhel6.x86_64 conflicts with file from package Percona-Server-shared-51-5.1.59-rel13.0.325.rhel6.x86_64 file /usr/lib64/mysql/plugin/libfnv_udf.a from install of Percona-Server-shared-55-5.5.16-rel22.0.189.rhel6.x86_64 conflicts with file from package Percona-Server-shared-51-5.1.59-rel13.0.325.rhel6.x86_64 file /usr/lib64/mysql/plugin/libmurmur_udf.a from install of Percona-Server-shared-55-5.5.16-rel22.0.189.rhel6.x86_64 conflicts with file from package Percona-Server-shared-51-5.1.59-rel13.0.325.rhel6.x86_64 Error Summary -------------
Para solucionarlos, detallo a continuación los pasos.
- Agregar el respositorio oficial
shell> rpm -Uhv http://www.percona.com/downloads/percona-release/percona-release-0.0-1.x86_64.rpm Retrieving percona.com/.../percona-release-0.0-1.x86_64.rpm Preparing...######################################### [100%] 1:percona-release################################# [100%]
o lo agregamos manualmente:shell> vi /etc/yum.repos.d/Percona.repo [percona] name = CentOS $releasever - Percona baseurl=http://repo.percona.com/centos/$releasever/os/$basearch/ enabled = 1 gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-percona gpgcheck = 1Si hacemos esto, también tenemos que agregar la clave GPG del repositorio,shell> vi /etc/pki/rpm-gpg/RPM-GPG-KEY-percona
El contenido está en Percona GPG key. - Actualizamos el sistema con el nuevo repositorio. Esto nos actualizará ciertas librerías de mysql por las de percona.
shell> yum update
- Buscar el software a instalar, en nuestro caso la versión 5.5 de percona.
shell> yum search percona ... Percona-Server-client-55.x86_64: Client Percona-Server-devel-55.x86_64: Devel Percona-Server-server-55.x86_64: Server Percona-Server-shared-55.x86_64: Shared Percona-Server-test-55.x86_64: test ...
- Al instalar la versión 5.5 de Percona-Server, esta falla, tal como detallamos al inicio.

Para solucionarlo, simplemente desinstalamos el paquete "Percona-Server-shared-51-5.1.59-rel13.0.325.rhel6.x86_64", que se instaló al realizar el update. Si no se realiza el update, entraría en conflicto con el paquete "mysql-libs-5.1.52-1.el6_0.1.x86_64".
shell> rpm -qa |grep Percona Percona-Server-shared-51-5.1.59-rel13.0.325.rhel6.x86_64 Percona-Server-shared-compat-5.5.16-rel22.0.189.rhel6.x86_64 shell> rpm -e Percona-Server-shared-51-5.1.59-...
- Volvemos a intentar instalar la versión 5.5 del servidor y ahora vemos que sí funciona.
shell> yum install Percona-Server-server-55.x86_64 ... Installing : Percona-Server-shared-55-5.5.16-... 1/2 Installing : Percona-Server-server-55-5.5.16-... 2/2 ... Complete!
- Aprovechamos para instalar también el cliente mysql-percona.
shell> yum install Percona-Server-client-55.x86_64 ... Installing : Percona-Server-client-55-5.5.16-... 1/1 ... Complete!
- Creamos el fichero de configuración de mysql, /etc/my.cnf con los parámetros que interesen.

- Creamos la estructura de la base de datos necesario para comenzar a funcionar.
